SrTiO\(_3\)  is arguably one of the most intensively studied materials of the perovskite family [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}.
Under ambient conditions SrTiO\(_3\)  is an insulating paraelectric, however a transition to ferroelectric phase can be induced by numerous mechanism with relatively low activation energy.
The temperature-strain phase diagram of SrTiO\(_3\)  is, at low temperatures, characterized by a very small region of paraelectricity with a ferroelectric phase emerging for small strains [8]}.
With increasing temperature the paraelectric region widens, yet, ferroelectricity remains accessible even above room temperature for high enough strain [4]}.
The proximity of the ambient paraelectric phase to a ferroelectric phase in the phase diagram is also underlined by the possibility to induce the phase transition through oxygen isotope substitution [5]} or by applying an intense laser pulse [6]}, [7]}.
